虎耳草根、茎、叶中岩白菜素的含量研究

Study on the Content of Bergenin in Roots,Stems and Leaves of Saxifraga stolonifera

目的:比较贵州不同地区虎耳草根、茎、叶中岩白菜素的含量差异,为其合理用药及质量控制提供科学依据。方法:采用高效液相色谱法对虎耳草不同部位的主要药效成分岩白菜素进行定量分析。结果:贵州不同产地虎耳草的同一药用部位中岩白菜素的含量具有一定差异;同一地区产的虎耳草不同部位岩白菜素的含量也不尽相同,叶子中岩白菜素含量高于茎中,根中的岩白菜素含量最低。结论:本研究建立了虎耳草根、茎、叶中岩白菜素的含量测定方法,该方法准确、简便、快速、稳定、重现性好,可以作为虎耳草全面质量评价的方法之一。

Objective：To compare the differences of bergenin content in different parts of S.stolonifera from different regions in Guizhou province,and provides the scientific basis for reasonable medication and quality control of S.stolonifera.Method： The bergenin content in different parts of S.stolonifera was quantitative analyzed by HPLC.Result： The difference of bergenin content in identical part of S.stolonifera from the different regions was significant,and the bergenin content in the different parts of identical S.stolonifera was different too;and that in leaves was better than in stems,which in the roots was the lest.Conclusion： The method for determination of bergenin in the different parts of S.stolonifera was established,which was exact,simple,fast,stable and reproducible so that may be used as one of the methods for quality evaluation of S.stolonifera.
